Inferior Vena Cava Anatomy. The inferior vena cava (IVC, also known as the posterior vena cava) is a large diameter vein that is located posterior to the abdominal cavity and runs alongside of the right side of the vertebral column (thus making it a retroperitoneal structure), with the aorta lying laterally on the left of the IVC.fter circulating through the body systemically, deoxygenated blood returns to the right atrium of the heart through either the superior vena cava, which drains the upper body, or the IVC that drains everything below the diaphragm, including the lower trunk, abdomen, pelvis, and lower limbs.

Inferior Vena Cava The inferior vena cava is the largest vein in the human body. It collects blood from veins serving the tissues inferior to the heart and returns this blood to the right atrium of the heart.he inferior vena cava and its tributaries drain blood from the feet, legs, thighs, pelvis and abdomen and deliver this blood to the heart. Many one-way venous valves help to move blood through the veins of the lower extremities against the pull of gravity.

Medical Definition of Vena cava Vena cava: The superior vena cava is the large vein which returns blood to the heart from the head, neck and both upper limbs. The inferior vena cava returns blood to the heart from the lower part of the body. The return of blood via the vena cava can be compromised and cause disease. For example, in the superior vena cava syndrome, the symptoms that result from compression of the large vein that carries blood down to the heart. The superior vena cava is located in the middle of the chest and is surrounded by rigid structures and lymph nodes. The structure bordering the superior vena cava include the trachea, aorta, thymus, right bronchus of the lung and pulmonary artery.

Inferior vena cava The inferior vena cava empties into the right atrium of the heart. The right atrium is located on the lower right back side of the heart. The inferior vena cava runs posterior, or behind, the abdominal cavity.This vein also runs alongside the right vertebral column of the spine.The inferior vena cava is the result of two major leg veins coming together.he inferior vena cava is also referred to as the posterior vena cava.

Critical Care Trauma Centre These venules become progressively larger vessels called veins. The vena cava are the two largest veins that carry blood into the right upper chamber of the heart (the right atrium). The superior vena cava carries blood from the brain and arms into the top of the right atrium. The inferior vena cava carries blood from the legs and abdominal cavity into the bottom of the right atrium. The vena cava are also called the central veins. Central venous catheters are inserted with the tip in or close to the superior of inferior vena cava. Blood is pumped from the right side of the heart into the blood vessels of the lung.

Tributaries of the Inferior Vena Cava The inferior vena cava, the largest vein in the human body, transports blood from the lower limbs, most of the back, the abdominopelvic viscera and the abdominal walls to the right atrium. It is formed by the union of the common iliac veins at the level of the body of L5. During its course, it receives many veins referred to as tributaries of the inferior vena cava. This article will discuss the anatomy of these tributaries in detail, followed by any relevant clinical notes.

Tributaries of the Inferior Vena Cava Close to the inferior vena cava, it is found anterior to the aorta and inferior to the superior mesenteric artery. At the level of the T12, the right suprarenal vein drains into the inferior vena cava. The inferior phrenic veins drain into the posterolateral aspect of the inferior vena cava at the level of T10. The left inferior phrenic vein drains higher than its right counterpart and is found superior to the oesophageal opening in the diaphragm.
